Meaning & History
Probably intended to mean "good spear" from Welsh rhon "spear" and da "good", but possibly influenced by the name of the Rhondda Valley in South Wales, which means "noisy". It has been in use only since the 20th century. Its use may have been partially inspired by Margaret Mackworth, Viscountess Rhondda (1883-1956), a British feminist.
